He gets a job as a cab driver and finds himself drawn to a 9-year-old who collects waste paper in the neighborhood. KIM Hyoung-do, a publisher whose soul was destroyed when he lost his child to OH Sung-chul, spots OH Sung-chul and follows him, bent on revenge. One day, KIM Hyoung-do witnesses OH Sung-chul’s desperate attempt to hang himself.
